对福建省永春县50年生油杉Keteleeria fortunei人工林的生物量进行研究。结果表明，在单株油杉地上部分，树干的生物量最大，为218.29 kg，树叶的生物量最小，仅为15.44 kg；地下部分生物量最大的是直径大于15.0 cm的根桩，达52.84 kg，最小的是小于1.0 cm的毛细根，仅为0.84 kg。油杉林分不同部位生物量分配：树干＞树根＞树皮＞树枝＞树叶。在油杉人工林生态系统中，油杉乔木层生物量为699.57 t·hm-2，林分净生产力为13.99 t·hm-2·a-1，林下植被层生物量为11.22 t·hm-2，凋落物层生物量为5.35 t·hm-2。

A study on biomass of 50-year-old Keteleeria fortunei plantation in Yongchun, Fujian province was carried out. The results showed that on aboveground part of K. fortunei, the average biomass of the trunk was the maximum of 218.29 kg per plant, the average biomass of the leaf was the minimum of 15.44 kg per plant. In underground part of K. fortunei, the biomass of the root whose diameter was greater than 15.0 cm was the maximum of 52.84 kg per plant, and the biomass of the root whose diameter was less than 1.0 cm was the minimum of 0.84 kg per plant. The biomass distribution of different organs followed an order as trunk>root>bark>branch>leaf. The biomass of arbor layer was 699.57 t·hm-2, the net productivity of forest stand was 13.99 t·hm-2·a-1, the biomass of undergrowth vegetation layer was 11.22 t·hm-2, the biomass of litter layer was 5.35 t·hm-2.
